Abstract:
Prophylaxis with nucleos(t)ide analogue (NA) is recommended to prevent hepatitis B virus (HBV) reactivation in hepatitis B surface antigen (HBsAg)–positive patients receiving rituximab-based B-cell depletion therapy. However, little is known about the risk of clinical relapse after withdrawal of NA. Methods We retrospectively analyzed 77 noncirrhotic HBsAg carriers with hematological cancer who received rituximab-containing chemotherapy. All of them received either prophylactic entecavir or tenofovir therapy. The risk of clinical relapse and hepatic decompensation after cessation of NA was explored. Results Clinical relapse and hepatic decompensation developed in 25 (32.5 %) and 11 (14.3 %) of the patients, respectively, and 2 patients died of hepatic decompensation. Most of the hepatic events occurred within 1 year (20 of 25; 80.0%) after stopping NA. A higher pretreatment viral load (≥2000 vs & lt;2000 IU/mL) was associated with increased risks of clinical relapse (hazard ratio, 3.47; 95% confidence interval, 1.56–7.73) and hepatic decompensation (9.91; 2.14–45.92). Of 51 patients with pretreatment viral load & lt;2000 IU/mL, clinical relapse occurred in 10 (19.6 %) and hepatic decompensation in 2 (3.9%). Conclusions Pretreatment HBV DNA ≥2000 IU/mL is associated with increased risk of liver-related disease after cessation of prophylactic NA therapy in patients who received rituximab-containing chemotherapy.
